2016-11-21ci: Decrease hugepages size for VERIFY&MERGE jobsMartin Klozik1-9/+0
VSPERF by default requires allocation of hugepages with total size of 10GB. However for MERGE and VERIFY jobs less memory is required and default size of 10GB can cause issues. Thus amount of memory was limited and other minor enhancements were introduced: * sysstat system package is installed at nodes running VERIFY and MERGE jobs * WHITELIST_NICS was set to empty list by default to avoid automatic bind of NICs to DPDK. Old default value could cut off network connection to DUT. * imports were fixed at both integration.py and testcase.py JIRA: VSPERF-391 Change-Id: Ic07d68f4591ae697c1b8edeae6c0cffe47c065ce Signed-off-by: Martin Klozik <martinx.klozik@intel.com> Reviewed-by: Al Morton <acmorton@att.com> Reviewed-by: Christian Trautman <ctrautma@redhat.com> Reviewed-by: Bill Michalowski <bmichalo@redhat.com> Reviewed-by: Antonio Fischetti <antonio.fischetti@intel.com>
2016-10-27teststeps: Generic support of step driven testsMartin Klozik1-184/+8
In the past, step driven testcases were supported only by integration testcases. This patch adds generic support of TestSteps for both integration and performance testcases. Step driven test were improved to support modification of existing deployment. As part of the patch a refactoring of traffic controllers were performed. Traffic controllers were modified to support trafficgen-off and trafficgen-pause modes in all possible ways of trafficgen invocation.

2016-10-05integration: Test vHost User numa awarenessMartin Klozik1-11/+26
Open vSwitch with DPDK can optimize memory usage in case of NUMA architecture to avoid unnecessary memory access across NUMA slots. In a nutshell, PMD threads serving virtual NICs are co-located at the same NUMA slot as QEMU instance, which is using these NICs. This patch adds new (functional) integration testcase, which verifies OVS vHost User numa awareness feature. Step driven test objects were updated to allow a call of OS utilies and evaluation of conditions. Also the documentation was updated with the list of supported test objects and their methods.

2016-10-03bugfix: Correct VM handling by integration testsMartin Klozik1-3/+15
Patch with multi VM support has changed the way how data are copied into the shared folder. Also new support of GUEST_ options expansion requires proper initialization with exact number of VMs involved in the test. Code of class specific to integration tests was updated to initialize both GUEST_ options and VM shared dir correctly. Original values of all GUEST_ options are restored after the testcase execution. So other TCs can use original values for configuration expansion to required number of VMs. JIRA: VSPERF-361 Change-Id: Ic1149fbc73f73a66982bb64173b2217e55597200 Signed-off-by: Martin Klozik <martinx.klozik@intel.com> Reviewed-by: Maryam Tahhan <maryam.tahhan@intel.com> Reviewed-by: Al Morton <acmorton@att.com> Reviewed-by: Christian Trautman <ctrautma@redhat.com> Reviewed-by: Bill Michalowski <bmichalo@redhat.com> Reviewed-by: Antonio Fischetti <antonio.fischetti@intel.com>
2016-08-09integration_cleanup: Force testcase cleanup to always runChristian Trautman1-86/+87
During testcase development on the integration side, if namespaces are used or veth ports and an exception is raised. The namespaces and veth ports are not properly cleanup up because the run_finalize does not get executed. This patch wraps the testing block in a try block where a finally will ALWAYS execute the run_finalize thus preventing the possiblity of leftover testing artifacts.

2016-07-07Namespace_veth: Add funtionality for network namespace, veth portsChristian Trautman1-0/+7
Adds functionality for network namespaces and veth/peer ports to connect the namespaces. The namespaces are tracked outside of default Linux namespaces to prevent possible disruption of work outside of VSPerf where a user may create a namespace and the cleanup code deletes it. The cleanup code only removes namespaces and veth ports created inside the testcase.

2016-04-27integration: Support of PVP and PVVP integration TCsMartin Klozik1-7/+32
Integration TC support has been enhanced to support PVP and PVVP scenarios. Definition of integration testcases have been modified to use a sort of macros for repetitive parts. Additional improvements were introduced: * instances of testcases are created only for testcases selected for execution * new TC definition options allow to define test specific vswitch, VNF, traffic generator and test options * tests filter applied on pattern specified by --tests allows to define negative filter only; In that case list of all tests is used as base for negative filter. * traffic values defined within teststep passed to send_traffic is merged with default values; This is essential for execution of TCs with linux_bridge or SRIOV support. It also simplifies integration TC definition * typos removed Change-Id: Icb734a7afd7e5154f27a8ff25615a39e01f58c27 JIRA: VSPERF-213 JIRA: VSPERF-216 Signed-off-by: Martin Klozik <martinx.klozik@intel.com> Reviewed-by: Maryam Tahhan <maryam.tahhan@intel.com> Reviewed-by: Al Morton <acmorton@att.com> Reviewed-by: Christian Trautman <ctrautma@redhat.com> Reviewed-by: Brian Castelli <brian.castelli@spirent.com>
2016-04-14sriov: Support of SRIOV and Qemu PCI passthroughMartin Klozik1-2/+2
Generic support of SRIOV has been added. Virtual interfaces can be used in multiplei scenarios instead of physical NICs. Virtual functions can be directly accessed from VM by PCI passthrough method. Another option is to use VFs with vSwtich to evaluate impact on performance. Additonal modifications: * Automatic detection of NIC details has been added to simplify configuration. * Obsoleted configuration options have been removed. * Logging usage within vsperf script was fixed. * Vsperf main was refactored and final cleanup function added. * Configurable forwarding mode of TestPMD executed inside VM.

2016-03-21integration: Support of integration testcasesMartin Klozik1-0/+173
Generic support for integration testcases with first set of tests for vswitch testing. New test option "TestSteps" has been introduced to define test step by step directly in configuration file. In case that this concept will be accepted, there are plenty of possibilities for future improvements. For example: * use it also for performance tests without explicit call of validation methods * introduce step macros for repetitive scenarios, so new tests can be easily written * further generalization, which would go beyond usage of controllers and will operate directly with vswitch, vnf and trafficgen objects Change-Id: Ifad166c8ef9cfbda6694682fe6b3421e0e97bbf2 JIRA: VSPERF-212 Signed-off-by: Martin Klozik <martinx.klozik@intel.com> Reviewed-by: Maryam Tahhan <maryam.tahhan@intel.com> Reviewed-by: Al Morton <acmorton@att.com> Reviewed-by: Christian Trautman <ctrautma@redhat.com> Reviewed-by: Brian Castelli <brian.castelli@spirent.com>
